Training Wheels - Nissan 240SX

There's no point in building an engine so bulletproof if you're not going to add ridiculous amounts of boost, and that was exactly what G-Dimension did, by way of a completely custom turbo setup. At the heart of the system is a Garrett GT30R, which hangs on to a tubular manifold from Wasabi Garage that has been modified to accommodate the turbo. The turbo spits hot air through custom piping into a Blitz front-mount intercooler, and is then channeled to the engine via 90MM Q45 throttle body atop a GReddy manifold. On the hot side of the equation, air is funneled through a custom downpipe (also by G-Dimension) through an A'pexi Dual N1 exhaust. Unused exhaust pressure filters through a TiAL 44mm wastegate.

Power is nothing without control. To keep Jack's new beast in check, G-Dimension used an A'pexi Power FC and AVC-R boost controller in conjunction with a GReddy turbo timer. Top Fuel's 60mm boost, water temp and oil pressure gauges give Jack a means by which to check vitals.

The combination of goodies net Jack 447 hp on California's 91-octane swill, which says a lot when you consider he's making 380 lb-ft of torque to boot. That kind of power will send the 2700-pound S14 flying down the highway and should make for an absolute monster on any track day. Back in G-Dimension, a fueling solution was necessary to keep the big Garrett wheel happy. In went a Tomei fuel pump along with their 740cc injectors and a NISMO fuel pressure regulator.

The crankshaft churns the power through a stock RB25DET transmission equipped with an OS-Giken twin plate clutch and a NISMO slave cylinder. A custom one-piece steel driveshaft matches with a Tomei clutch-type LSD.

In order to make the RB25-equipped S14 capable on the circuit, the car was sent over to Alex Pfeiffer of Battle Version in City of Industry to have a set of Racing Logic coilovers installed and the car corner balanced. While the car was in the air, it received a race alignment using Battle Version links and a Largus anti-roll bar. Tein rods and ends work in tandem with Battle Version front lower control arms and adjustable tension rods to translate wheel movement to the coilovers. In the rear, Battle Version adjustable traction rods, camber rods, toe rods and rear lower control arms ensure there is zero slop in the geometry.

Bouncing at the end of said custom geometry are 18-inch Work XSA wheels, nine inches wide up front and ten in the rear. They squeeze inside 235/35/18 and 265/35/18 Advan Neova rubber, respectively. Project Mu stepped in to provide the brakes that were necessary to fill the gap behind the massive wheels. Its four-piston front kit works with 345mm rotors and stickier pads, which are also employed in the stock rear calipers. Finally, Project Mu's own fluid and stainless steel lines are used.

At this point, Jack decided he was going to go the distance, and added wide-body fenders, front and rear. The rear fenders have been molded in and the hood has been replaced with a vented carbon-fiber unit. Last, the entire thing was slathered in M3 blue paint and added S14 Kouki front and rear lights.

What started as a cheap way of getting on the track has turned into the most cherished item in Jack's garage (and it's not the cheapest, either), but he says that won't stop him from getting on the track. Judging by the extremism used in the creation of his wild 240, we don't imagine he'll give up on learning to drift without a serious fight.
